2 Claims.

This invention relates to devices to hoist. bundles of shingles, or other material, to a roof or other elevation, and especially to such a hoist as may be mounted on a ladder.

The objects of my invention are to provide, first, a means of securing the ladder in place to withstand the twisting action of the load which is eccentrically supported thereby; second, a means of removably securing to a ladder, at any desired point thereon, a crane adapted to turn on its supported axis, and adapted to support the load to be lifted; and third, a device which may be quickly and easily attached to or detached from the ladder, easily transported to the place at which it is to be used, and which is rugged in construction and effective in use.

I attain these and other objects by the devices, mechanisms and arrangements illustrated in the accompanying drawing, in Which- Fig. 1 is a perspective View of a ladder equipped with my improved hoist, in use; Fig. 2 is a side elevation of a portion thereof; Fig. 3 is a section thereof taken on the line 3--3 in Fig. 2; and Fig. 4 is a section thereof taken on the line 4--4 in Fig. 2.

Similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawing it will be seen that the ladder is of the usual construction, comprising runners I and a plurality of steps or rungs 2 secured thereto, and that it is shown as leaning against the edge of a roof 3 forming part of a supporting building 4.

The base of the ladder may be secured in place by the stakes 5, or otherwise, but it should be secured in some effective manner. The upper part of the ladder is secured in place and held from twisting under the eccentric load supported thereby, by means of the two metal bars 6, each of which is hooked over a runner I at one of the steps 2 and fastened to a board of the roof 3, or to a separate piece which may be fastened to the roof.

A base for the crane is formed of a cross-bar 1, preferably formed of a piece of angle-iron, adapted to be hooked over and lie on one of the steps 2 of the ladder, and being notched at 8 to receive the runner I of the ladder, and extending out laterally from the ladder to receive the carrier bar 9. This carrier bar 9 is preferably formed of a piece of angle-iron, attached to the extended end of the front angle-iron 'I by means of a bolt and wing nut II), and lying against the outer side of the runner I of the ladder. The rear end of the carrier 9 is connected to the other end of the front cross-bar I by means of the diagonal brace bar II bolted to the parts 'I and 9. 'Ihe bolt I2 which secures the part I I to the part 9 is long and also secures the cylindrical lug I3 in position on top of the end of the brace bar I I.

The rear end of the base formed by the parts 1, 9 and II is held up or supported by means of the strap` bar I4, secured thereto by the bolt and wing-nut I5 and to the hereinafter described bearing block by means of one of the bolts and wing-nuts thereof. neatly in the lower end of the crane post, as hereinafter described, whereby the end' of the said post is held firmly in position but is free to turn thereon.

A bearing block I6, adapted to receive the post of the crane, is clamped to the runner I of the ladder by means of the two bolts II and the plate I8. The plate I8 is placed on the inner side of the runner I while the bearing block I6 is placed in corresponding position on the outer side thereof, the bolts Il passing to the front and rear of the said runner. The bolts I'I are provided with suitable wing-nuts I9. The upper end of the above described strap bar I4 is attached to the bearing block I6 by one of the said bolts I'I and nut I9.

The crane, which comprises a cylindrical post 20, may be conveniently made of a suitable piece of iron. pipe, iits over the lug I3 and in the hole of the bearing block i6, is supported by the base and the said bearing block, and is bent at its upper end to provide an arm 2I on the end of which a suitable pulley block 22 may be removably hung. The crane can turn freely in the bearing block and on the pivot lug I3 to bring the arm 2I and pulley 22 to any desired position.

The load 23 is attached to the hoist rope 24, passing through the block 22, and is raised to the desired level by pulling on said rope 24, in the usual manner. When it is thus raised the arm 2I is swung over the roof, or other place on which it is to be deposited, and the load is then lowered thereon and released.

It is evident from the above description that the entire hoist apparatus may be disassembled from the ladder and easily transported therewith to any location where it is to be used; that it may there be quickly reassembled in any desired posiytion on the ladder and adjusted thereon; and

that it is then ready for use in hoisting any material up to the roof. Also it is to be understood that many variations in the details of construction may be made therein without departing from The cylindrical lug I3 fits the spirit of my invention as outlined in the appended claims.

Having, therefore, described my invention what I claim and desire to secure by Letters Patent 1. A detachable hoist for ladders having runners and steps, comprising a cross-bar adapted to lie on one of. the steps and having a vertical leg in Contact with the rear side of the step and cut away adjacent one end to receive the ladder runner; a carrier bar attached to the end of said cross bar and extending rearward therefrom, and lying outside of said ladder runner; a diagonal brace bar attached to the free ends of said crossbar and said carrier bar, thereby forming therewith a triangular base; a bearing block clamped to the ladder runner at a point above said triangular base, and including a bearing; a strap bar attached to said bearing block and the free end of said carrier bar, whereby said strap bar and the ladder step support said triangular base; and a crane post supported by said triangular base and journalled in said bearing.

2. A detachable hoist for ladders having runners and steps, comprising a cross-bar adapted to lie on one of the steps and having a vertical leg in contact with the rear side of .the step and cut away adjacent one end to receive the ladder runner; a carrier bar attached to the end of said cross-bar and extending rearward therefrom, and lying outside of said ladder runner; a diagonal brace bar attached to the free ends of said cross-bar and said carrier bar, thereby forming therewith a triangular base; a bearing block clamped to the ladder runner at a point above said triangular base, and including a bearing; a strap bar attached to said bearing block and the free end .of said carrier bar, whereby said strap bar and the ladder step support said triangular base; a crane post supported by said triangular base and journalled in said bearing; and a lug secured to said carrier bar and entering a socket inthe end of said crane post and adapted to hold said crane post in position on said carrier bar.
